Abstract
The International Union Against Cancer (UICC) recommends renal angiography to T-stage renal cell carcinoma. 96 angiograms were reviewed, staged and compaired with the histopathologic staging. 55% of renal cell carcinomas were overstaged and 4% were understaged. We conclude that renal angiography cannot be used for precise preoperative staging of renal cell carcinoma.
